Acute Posthemorrhagic Anemia is associated with higher LOS in Major Ortho & Colorectal Procedures



Researchers in the past have studied associations of Anemia with health outcomes such as LOS & Readmission rates (see 4 studies listed at the end of the article). Similarly, we examined our database to analyze the impact on Length of Stay (LOS) when Acute Posthemorrhagic Anemia was present for major Ortho & Colorectal procedures.


The results are shown in the below chart & table.



CategoryDRGAvg. LOS with Acute Posthemorrhagic AnemiaAvg. LOS without Acute Posthemorrhagic AnemiaAvg. LOS Difference
Ortho470 - MAJOR JOINT REPLACEMENT OR REATTACHMENT OF LOWER EXTREMITY W/O MCC321
Ortho483 - MAJOR JOINT/LIMB REATTACHMENT PROCEDURE OF UPPER EXTREMITIES312
Ortho469 - MAJOR JOINT REPLACEMENT OR REATTACHMENT OF LOWER EXTREMITY W MCC761
Colorectal330 - MAJOR SMALL & LARGE BOWEL PROCEDURES W CC871
Colorectal329 - MAJOR SMALL & LARGE BOWEL PROCEDURES W MCC16124

As the above data table shows, Ortho & Colorectal DRG procedure groups have a 1-4 day difference when Acute Posthemorrhagic Anemia was present versus when it was not present.
